Hibernate version:2.1.7

Mapping documents:

Code between sessionFactory.openSession() and session.close():

Code:

try{
            Session hibSess = ks.getHibernateSession(); 
         
         Query query = hibSess.createQuery(strBuffQuery.toString());   
         
         if(log4j.isDebugEnabled()){
             log4j.debug("Query: "+strBuffQuery);
         }
         
         
         ScrollableResults rs = query.scroll();
         
         Object [] objRow = null;
         while(rs.next()){
            objRow = rs.get();
            alResult.add(objRow);            
         }
         } catch (HibernateException he){         
            throw new KevusPersistenzException(he);
         }

Name and version of the database you are using:mckoi 1.0

Debug level Hibernate log excerpt: error

Code worked with former implementation from hibernate2.jar (Version 2.1.2) . What has changed?

looking at the code

Code:

if (result != null && result.getClass().isArray()) {
            currentRow = (Object[]) result;
         }

then i would say that line cannot throw that exception....try to use a debugger to see what goes on.
